Discussion

The BGS archive holds little information on the groundwater resources of the D.R.Congo. References from the
pre 1960 period include a series of Geological Survey reports, most produced in French, describing aspects of
geomorphology and geology relevant to groundwater occurrence. Notably Snel (1957) outlines groundwater
occurrence, including in his description one of the few hydrogeological maps of the Congo basin.

Of the three
references available from the 1961-1990 period, UNDP (1989) reviews the hydrogeology of the DRC
whereas Service Geologique (1966) is part of a geological map description outlining the hydrogeology of that area and the last
describes weathering patterns within Precambrian Basement rocks.

References from the post 1991 period primarily
describe socio-economic conditions related to water supply as produced by an NGO and International Aid
organisations (UNICEF and the World Bank).
